In 1952, Mme Muller of Chenil du Clos Saint-Jacques urged Rudy Robinson (Candide kennel in US) to import one of her expected Tervueren puppies. She described the litter as follows: "Last May, I went to Zurich with one of my best female Tervueren, Yalou du Clos St Jacques, winner female from Belgium 1951, to have puppies from Urvinioul, the most beautiful male Tervueren that I have ever seen in my life - Urvinioul belongs to Mr Barr, the well-known judge for Belgian Sheepdogs in Suisse. The tenth of July Yalou littered 4 < 8 puppies. How beautiful! I have never seen such homogeneousness: they are all alike. Same fur, colour, with a splendid dark mask. They are perfect, they are afraid of nothing.....shooting, noise, they remain still. Included I send you a photo. My husband and I are not willing to sell one in France, but in America it's different. That would be a good publicity for the Clos St Jacques. Would you like to have one?"
Rudy was interested in importing the Tervueren variety, but he had no wish to be the only one in the country with them. He discussed the subject with the Krohns, who were also intrigued by the photographs and descriptions. It was decided that Rudy would take a male, with the Krohns and Rudy's secretary, had no more males from the Yalou litter. She did still have two females, but she felt they were, at seven months, too old to ship safely.
Rudy asked Mme Muller to select the puppies from any of her new litters, leaving the choice to her after pointing out that they would be the foundation dogs for Tervueren in this country.
